Management of erasure or retention of user data stored in data stores

A computer-implemented method, comprising:

• in response to a request to delete a group of data associated with a user account from a group of database components, analyzing, by a system having a processor and a memory, a group of rules and information associated with the user account, wherein the group of rules is applicable to the group of database components and relates to data deletion and data retention, and wherein the information comprises an account status associated with the user account;
• based on the analyzing of a first rule of the group of rules and the information, determining, by the system, a first permissibility status for deletion of a first portion of the group of data from the group of database components, the first permissibility status indicating that the first portion of the group of data is eligible for deletion;
• based on the analyzing of a second rule of the group of rules and the information, determining, by the system, a second permissibility status for deletion of a second portion of the first portion of the group of data from the group of database components, the second permissibility status indicating that the second portion of the first portion of the group of data is ineligible for deletion;
• based on the determined permissibility status, automatically deleting a third portion of the group of data, the third portion comprising all data in the first portion that are not in the second portion;
• in response to the erasure of the third portion of the group of data, generating mask data corresponding to the third portion of the group of data;
• and
• replacing the erased third portion in the group of database components with the corresponding mask data, the mask data configured to maintain a validity of a link to the third portion.

A machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• receiving an erasure request that requests a set of data associated with an entity account be erased from a set of data storage components that stores sets of data associated with entity accounts, comprising the set of data associated with the entity account;
• in response to the erasure request, evaluating a set of rules and information associated with the entity account, wherein the set of rules is determined based on a set of legal or contractual obligations associated with the set of data storage components and is related to data erasure and retention, wherein the set of rules comprises a first rule and a second rule, and wherein the information comprises an account activity status and an erasure restriction status associated with the entity account;
• based on the evaluating of the first rule of the set of rules and the information associated with the entity account, determining an eligibility status for erasure of a first portion of the set of data from the set of data storage components;
• based on the evaluating of the second rule of the set of rules and the information associated with the entity account, determining an ineligibility status for erasure of a second portion of the first portion of the set of data from the set of data storage components;
• based on the determined permissibility status, automatically deleting a third portion of the set of data, the third portion comprising all data in the first portion that are not in the second portion;
• in response to the deletion of the third portion of the set of data, generating mask data corresponding to the third portion of the set of data;
• and
• replacing the deleted third portion in the group of data storage components with the corresponding mask data, the mask data configured to maintain a validity of a link to the third portion.
